Application filed November 30I 1903. Serial No. 183,098. (No model.)

To all whom t may oon/cern,.-

Be it known that I, CHARLES B. HURST, a citizen of the United States` residing near Chillicothe, in the county of Ross and State of Ohio, have invented certain new and useful Improvements in Frames 'for Scales, of which the following is a specification.

' My invention relates to improvements in frames for Wagon and stock scales; and the object of my invention is to provide a concrete or similar frame which can be cheaply built and easily transportedl and which can be placed in position and is immediately ready for use.

- My invention consists in the constructions and combinations of parts hereinafter described, and set forth inthe claims.

In the accompanyingdrawings, Figure 1 is a perspectiveview of my device shown in position on its foundation, one of the sections being removed to better illustrate some of Fig. 2 is a View in perspective of the end of one of the frame-sections, and Fig.v 3 is a perspective view of the under side of same. Figs. 4, 5, and 6 are detail views of the connecting devices for the respective framesections. Fig. 7 is a view illustrating a method sometimes employed for building up a section for the purpose of enlarging the frame. Fig. 8 is a modiication of the fastening-bands.

Like parts are represented by similar reference characters in the several views.

In building up the supporting-frames for wagon and stock scales steel and wood have heretofore been employed for this purpose. The steel and wood frames, however, are expensive. Concrete'frames built up at the place where the scale is to be installed are objectionable in that a considerable length of time is required to allow them to become hard and'iirm enoughto permit a heavy load to be placed on the platform'of the scale and also owing to thejweather conditions, Which will prevent the construction of concrete frames duringA certain seasons of the year. To overcome theseV objections, I have provided a concrete framework which is built in sections and shippedto the place where the scale is to be installed and have provided'means for securely joining these sections together in such a manner that these frames can be made immediately ready to permit the scale to be put in use.

In the said drawings, a L represent the respective frame-sections, which are formed from concrete or similar'substance of a size which will be convenient forv transportation. Both ends of the respective sections a are for-med with rounded. recesses a', extending vertically the entire depth of the section, as shown, so as to forma round vertical opening between the respective sections when they are placed together in position to form the frame. The extreme ends of the respective sections are preferably beveled, as shown at a2, the adjacent ends of the sections .being beveled in opposite directions, so as to correspond to and Yiit eachj other, and thus form a firmer joint between the respective sections. After the respective frame-sections are in position on their foundation I have provided means for drawing the adjacent ends of the same firmly together. In each section a at the time of constructing the saine is embedded a band b', formed at one end with an eye which projects from one end of the section. The other end of the band b projects from the opposite end of the frame-section and receivesa loose engaging. hook b2. This end of the band is also screw-threaded tolreceive an adjustingnut 3 for said hook. When the sections are placed in position, the eye b' of one section will be engaged with the hook b2 of the adjacent section, and by turning up the nuts b3 of the respective rods the sections will all be united firmly together, the respective bands forming substantially a continuous retainingband. Also embedded in the respective sections are rods c, the ends of which project from the sections for a suitable distance 'and are formed with projecting portions or hooks c. I have shown two of these rods c for each section, one at the top and bottom at each side of the vertical center thereof; but more may be employed, if desired. Then the respective sections are tightened together by the and when this hardens thel sections are thus j intervening space between screwed up against the eye b to tighten the bands to form a continuous retaining-band for 2. In a scale, a frame formed in sections of continuously and iirmly joined togetherbyj Y plastic material such as concrete, krecesses reason of the 'projecting portions c ot' the rods c, which become embedded in the conformed in the respective ends of said framecrete plugs (Z. sections to form vertical openings between @represents the supports or connections Jfor `the adjacent ends of said sections, rods emthe platform-levers of the scale, which conbedded into said sections and adapted to pronections are held in position on the frame a j ject from the respective ends thereoi` into said by rods a and nuts 2, which rods extend openings, said rodshavinglaterally-projecting through the frame-sections (t and are secured portions attheir ends, and plastic material such to anchor-rods c3, which extend to anchors (2*, as concrete adapted to be tamped into said as shown,-to take the strain oi the scale-platopenings and embrace the laterally-projecting form and the load thereon from the frame-secportions of said rods, for the purpose specitions.

In a scale, a frame formed in sections of frame an additional section or 1 sections may plastic" material .such as concrete, bands in be provided by the means shown in Fig.' 7. said -sections adapted to engage with each Two adjacent sections c are separated for a other to form a continuous retaining-band distance equal to the enlargement desired, the through said sections, means fortightening the same inclosed said bands, recesses formed in the respective by temporary wallsf, as shown, and the space ends oi' said sections to form a continuous verthen lilled by tamping in concrete, the con tical opening between the respective sections, necting-bands t and the rods c being embedplastic material such as concreteadapted to ded in said concrete in the manner heretofore be tamped in said openings, and rods in addidescribed, the said band I) -being first tighttion to said retaining-band projecting from ened up to the desired degree to form a consaid Sections having lateral projections adapttinuation of the endless band formed by the ed to be embedded in said plastic material, rod-sections Z1, as described. substantially as and for the purposespeciiied. Then the frame-sections 4. In a scale, a frame formed in sections of sition on their' foundation, it is ofcourse usual plastic material such as concrete, a band emto provide an intervening layer of concrete or bedded in each of said sections formed at one mortar between the said sections and the founend with an eye, and adjustable means at the dation. If desired, rods g may beprovided,

opposite end of said band to engage the eye .which are embedded in the respective framesections and extend from the bottom thereof andare provided with projecting portions g, adapted to embed themselves in the concrete or mortar, and thus more firmly secure the same frame-sections in position.

In Fig. 8 I have shown -a modification in the manner of joining together the bands b. In this construction the end of the band formed with the eye 7) is bent at right angles to the band, and the eye is threaded over the end of the adjacent band, which is screwthreaded to receive the nut t, which can be are placed in po- 5.
